(a) the acceleration of each of the boxes

a1 = m/s2

a2 = m/s2

a3 = m/s2

(b) the tension in each string

T1 = N

T2 = N

I also have a rollercoaster question that I have not been able to solve:

The radius of curvature of a loop-the-loop for a roller coaster is 10.6 m. At the top of the loop, the force that the seat exerts on a passenger of mass m is 0.35mg. Find the speed of the roller coaster at the top of the loop.

I have no idea how to solve this, our book does not give a good related example. I would highly appreciate any help.
